So, basically, we don’t know that much on anything besides understanding it’s really complex and difficult to figure out.
This has always been true.
No it hasn’t. Many religions and spiritual texts covered all this stuff in just a couple of pages.
Please do show the spiritual texts which cover general and specific relativity.
The Bible says something about the earth and how it is good and the filament of the sky and something. The Bible that is, at least that’s what I read on the internet. Many fine people on the internet, the best people, but not me, I haven’t said it, but the best people probably. The best people say the earth may be - and I’m not saying it is but they are saying it - they say that the earth may be flat and that doesn’t take much text to cover I have heard.
Copernicus deserves a mention. Galileo’s problems resulted (in part) from him being a proponent of Copernicism after the church had declared it heresy.
Heliocentrism was suggested by Copernicus and Galileo built on that, including developing physics to the point where he couldn’t believe otherwise.
The heliocentric models predicted the orbits worse than epicyclic geocentric ones and that is the reason Galileo was told to shut up, the court transcript is like 99% science and then a single subordinate clause saying “it also contradicts the bible”.
Galileo insisted on circular orbits which was his downfall, ironically “because circles are perfect and god would furnish the universe perfect”: That kind of religious language while also being worse science than what was already established did him in. Kepler, based on Brahe’s data, was the first one to get a heliocentric model right and more accurate than the epicyclic ones.
Also earth doesn’t revolve around the sun. If anything both revolve around their shared centre of gravity but really it’s a matter of your frame of reference. Paraphrasing Archimedes: Give me a fixed point in the universe and I will move all your models.
The sun. Does the earth and moon orbit a gravitational center that they share? Does that center revolve around the sun? How imperceptible is this, considering the shared point is likely inside the earth given the difference between its mass and lua’s?
Does the earth and moon orbit a gravitational center that they share?

Relevant alt-text https://xkcd.com/1489/
I know I’m stupid but how do you see the alt text?
On mobile: long press on the comic itself
Know of any way to make Firefox not cut it off?
Does it just ellipsis off (…)?
One tap on the alt text fixes that
Oh nice. It’s some combination of you being awesome and me being stupid for not figuring that out.
I’m glad you can see the alt text! It’s the best part sometimes
Yeah, I’ve been feeling like I’ve only been getting half the experience with xkcd on mobile up to now. Full experience unlocked!
